You’re tired of the air you pay to heat and cool escaping through your cathedral ceiling, so you’re ready to have foam insulation installed.

How to Insulate a Cathedral Ceiling in an Existing Home
There are two methods to insulating a cathedral ceiling with foam insulation.
You can either drill holes and inject the foam or cut panels and spray the foam. One method of installation may work better compared to the other. It really comes down to what you and your contractor decide is best for your project.
While the installation processes are different, the results are the same as both injection foam and spray foam create the air barrier you’re looking for to stop air leakage.
That doesn’t really specifically answer your question, so let’s really break this down.
How to Insulate a Cathedral Ceiling with Injection Foam
Insulating the cathedral ceiling of your home with injection foam can be done by drilling holes into the cavity on either side of the peak.
The holes would be drilled in the middle of each cavity, so the installer can run the hose from the top to the bottom to ensure the cavity is full. The existing fiberglass in the cathedral ceiling can stay put, as the injection foam will compress it as it fills the space.
Once the foam has been injected, the holes are plugged, and a rough patch of drywall mud is applied over the plugged hole.
How to Insulate a Cathedral Ceiling with Spray Foam
Insulating the cathedral ceiling with spray foam requires a little more demo, but the installer is able to better see the foam expanding and filling the cavity.
Before the foam can be sprayed into the cavity, any existing insulation will need to be removed so the spray foam can adhere to the underside of the roof.
One- to two-foot strips would be cut through the middle of the stud cavities on either side of the peak. This way the installer can spray from the soffit up to the peak in each cavity.
Once the foam has been sprayed into the cavities, drywall is placed back over where the strips were cut and a rough patch of mud is spread over the seams.
Air Sealing Your Home
Whether the foam is injected or sprayed into your cathedral ceiling, you’ll notice a difference in the comfort level of your home.
No more air leaking through the roof. No more high energy bills.
